Hi all,
I’m sorry to bother, again… But I keep getting problems hope you can give me some advice.
I’m trying to test out L4re +L4Linux on X86 and ARM i.MX6. I downloaded the newest l4re-snapshot-2006082114. I built Fiasco with Intel Pentium Pro and Virtualization (did not change anything else).
I built L4re with Pentium Pro type CPU (everything else are default settings). Then I built L4Linux with the L4re builddir. I turned off 64-bit kernel, CPU selected Pentium-Pro, turned off most of the settings as the warning instructed.
These are the settings of L4Linux that I enabled:
Processor type and features:
* DMA memory allocation support
* Processor feature human-readable name
* Fast CPU feature tests
* Support for extended X86 platform
* Single-depth WCHAN output
* High memory support is OFF
* Enable bounce buffers
* X86 architectural random number generator
* Enable seccomp to safety compute untrusted bytecode
* Enable the LDT
Power Management and ACPI options:
* Suspend to RAM and standby
* device power management core functionality
* CPU Frequency scaling is OFF
Bus Options:
* PCI support
* PCI access mode is Direct
I was able to compile all three parts and build both iso image (for vmware fusion on macOS) and qemu simulator. I first tested hello, hello-cfg, hello-shared, frame buffer-example-x86, all of those works as expected.
However when I tried to build L4Linux-basic and L4Linux-mag-x86. Not of them works.
for L4Linux-mag-x86 the system shows a diagram “system is booting” then hang forever.
for L4Linux-basic the image boot but freeze soon. The screen shows:
l4cdds: No name given, not starting
brd: module loaded

moused: ps/2 mouse device common for all mice

Please press Enter to activate this console. clocksource: tsc: mask: 0xffffffffffffffff max_cycles: 0x2845e81c5f6, max-idle_ns: 440795276432 ns
clocksource: Switched to clocksource tsc
Initially I thought it might related RTC so I checked out all Real time clock in L4Linux, but it still the same. Any help would be appreciated.
Thanks
